DEBRANNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 738,669, datedSeptember 8, 1903.

Application filed December 29, 1902. Serial No. 137,003. (No model.)

a To aZZ whom it may concern.-

Be it known that we, SAMUEL S. FOOTE and JOSEPH O. MOKEE, citizens ofthe United States, residing at Caldwell, in the county of Canyon andState of Idaho, have invented:

certain new and useful Improvements in Debranning Apparatus; and we dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to new and useful improvements in millingappliances, and especially in the provision of a feeding-coil which isadapted for the purpose of pressing or compactinggrain within thecylinder, causing the same to choke and be in proper condition to beacted upon by a cone as a regulator or valve to retard the grainsufliciently tobe operated upon. I

More specifically the invention consists in the provision of afeeding-coil, the last turn of the coil being disposed at substantiallyright angles to the shaft on which it is car-' tried for a distanceequal to one-half of the circumference of the shaft and the extreme endbent at an inclination rearward to the twist of the coil.

ing the shape of the bent end of the worm...

Reference now being had to the details of the drawings by letter, Adesignates a conveyer-box, and B a cylinder which is positioned adjacentthereto and has a bore the wall of which is continuous with the innerwall of said conveyer-box, and G designates a hopper to theconveyer-box, and D is a shaft which passes through an aperture in theconveyer-box and has thereon a coil conveying- Worm E, which worm is ofthe ordinary construction, excepting the last turn of the coil, from thepoint F to F, is disposed with its outer periphery in a plane at rightangles to the length of the shaft instead of following the regularspiral course of the wing and the extreme end of the coil is bent backat an angle, as shown. By this provision of feedingworm having the lastturn of the spiral coil positioned as shown and described we are enabledto compact the wheat within the cylinder at such a consistency that itwill be satisfactorily fed out through the flaring portion of thecylinderand the regulating-cone. With the ordinary form of conveyor aspace is left between the end of the conveyer and the outlet for thewheat between the cone and concave, and in this space the bran fromwheat is mostly loosened and rubbed off,v

and with an ordinary conveyer trouble is met with invthe materialworking irregularly and Wheat would frequently come through withoutfilling the cylinder tightly and without choking; but by the provisionof a conveyer what we claim as new, and desire to secure by.

Letters Patent, is-

A debranningapparatus comprising a box, a cylinder communicatingtherewith, a shaft mounted in said box, a regulating-cone secured to theshaft, aconveyer-worm'on the shaft and having substantially one-half ofthe last turn of the worm disposed in a plane at right angles to theshaft and adjacent to the opening in the cylinder, and having its endbent at an inclination to the length of said shaft and toward themarginal edge of the adjacent turn of the worm, whereby grain may becompacted 0r choked within the cylinder, as set forth.

In testimony whereof we hereunto aflix our signatures in presence of twowitnesses.
